Hi, Mika and Greg-
Should this commit:
commit 6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095
Author: Mika Westerberg <mika.westerberg@linux.intel.com>
Date: Wed Oct 7 15:33:43 2015 +0300
HID: multitouch: Fetch feature reports on demand for Win8 devices
be backported to 4.3?
AFAICT the issue affects a range of Skylake systems, but only on Linux
4.3, because 4.2 and below don't have the intel_lpss driver and end up
driving the pad in compatibility mode, which isn't affected.

Looks reasonable to me, is it a clean "cherry-pick"? thanks, greg k-h ^ permalink raw reply [flat|nested] 5+ messages in thread

It is, and I've even tested it on a 4.3 kernel on my laptop. I'd prefer to get either Mika or Benjamin's ok first, though. --Andy ^ permalink raw reply [flat|nested] 5+ messages in thread

We limited the scope of it and made tests on a few hardwares when testing upstream. It was submitted during 4.3 rc cycles, so that's why it's in 4.4 and not 4.3.
